Application filed June 13, Y

T 0 all whom it may concern:

Be it known that LEIE MAN O. RnIDEN- EACH, a-citizen of the Unitedstates, residing at Detroit, in the county of Wayne and State of Michigan, hav invented certain new and of severe usage.

This invention relates to a spring seat construction and more particularly to an arrangement of parts whereby a pliable top is obtained that supports applied covering and fillingin such a way that it does not tend to sag between thesp'rings while the springs themselves are free to act independently in a measure, but at the same time are anchored rigidly against lateral displacement without the aid of clips or other like fastening means. g j

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings, Fig. '1 is aplan view, partially broken away and in section to disclose the lower frame construction, of a spring seat that embodies features of the invention;

Fig. 2 is a view in detail of a; transverse frame member with the end turns of springs attached thereto;

Fig. 3 is a view in section taken on or about line III-III of-Fig. 2.

Referring to the drawings, a base 1 is formed of suitable design with upright body springs 2 mounted thereon. The springs are disposed in rows and each pair of two. adjacent rows are interconnected by a pliant frame strip 3 of sufficient width not only to overlap the adjacent upper turns of the springs, but also to bridge over the interstices bet-ween the springsso as to prevent upholstering'that is applied to the structure, from sagging between the springs.

Where the strip overlies the upper or end turns 4 of the springs, the margins of the strip are inbent as indicated at 5 and crimped around the turns while at the ends, the strip is bent over as indicated at, 6 to Specification-of Letters Patent:

.enfold a rim 7, the latter of which is likewise I raanaa aaaae; i 2.

attached to'certain end turns ofthe springs by clips 8 or other suitable means;

Thebase of the structure may be" of I A border I preferred type but asherein indicated, is a replica of the upper rim frame. 7 member 9 is spanned by pliable strips 10, the end portions 11 of which are bent around the rim while the base turns 12'of the body springs which are; seated partially on the strips, are secured bythe int'urned or inbent marginal portions 13 thereof, there being other fastening members 14 where necessary to hold the outer springs to the-rim. I

When in use, any weight thatis carried by the springs is sustained not only at, the

mote thereto, since the pliable strips-cannot 1 point of application, but also atfp lacesrelocal deformation of each spring is possible .1 since the strips bend slightly to permit this.

.The connection between the strip andsprings reinforcesthe strip at this point of attachmentfbe'cause of the triple layers of material at these points. Between the springs, the; strip is freely bendable sojfar as the method of' attachment toth e rim I i frame permits this. As a result, a. spring structure is obta ned that presents a smoothexteriorwith broad supporting members for applied upholstery,

while at the same time, the top is soft and resilient. Thesprings are secured in posif tion without the aid of clips, save at the few points of attachment in the rim frame.

Obviously changes in the details of com I struction may be made without departing from the spirit of the invention and I. do not 1 i care to limit myself to any particular form or arrangement of parts.

v I claim asmy invention v 1. A spring cushion structure including border frame, crossstrips of pliant metal secured at their ends to said border frame,

the end coils of springs of adjacent rows disposed side by side and overlapping said j bers of the-frame parallel to said strips.

2. A spring cushionstructure including aborder frame, cross strips of pliant metal 100 and coiledsprings arranged in rows with secured at their ends to sa id border frame, and coiled springs arranged in rows With the end coils of springs of adjacent rows side by side and overlapping said cross strips, the opposed edges or said cross strips lying Within the coils being folded inwardly thereon, the remaining portions of the strips being flat and pliant. 7

3. A spring cushion structure including a 10 border frame, cross strips of pliant metal secured at their ends to said border frame,

and coiled springs arranged with their end coils overlapping said cross strips, the edges of sald cross strips lying Within the coils being'folded thereon, the outer rows of springs being secured to the portions of the frame parallel to said strips.

In testimony whereof I afiix my signature.
